At one point he aimed a drunken kick at his pal and later did a “silly walk” across a zebra crossing.

He was also seen fumbling with his mobile phone while leaning on some metal railings.

When finally admitting defeat and accepting his night was over, he fell against the window of a designer clothes shop.

He and Jake had arrived in LA on Thursday afternoon and were taken straight to their five-star hotel, The London.

It was Joey’s first time in Tinseltown. A source close to him told how “he’d had a few drinks on the plane” and was “very excited” about his two-week trip to Hollywood – intended to help him “crack the States”.

After changing into a grey checked shirt and jeans, Joey set off with Jake for the 1Oak Nightclub where Paris, 33, was holding a Halloween party.

A source at the club said: “Thursdays are a big night for 1Oak and it was full so nobody could get in unless their name was on the guest list.

“But Joey and Jake were up for a big night and they heard it was the place to be so he decided it was a no-brainer to hand over the cash and have his own table. He loved it in there, partying alongside Paris, but it didn’t last as long as he had hoped. He was politely asked to leave. Eventually he agreed to go but then he spent a while outside trying to get back in.”

An onlooker added: “Joey and his friend decided to walk along Sunset Boulevard where Joey was all over the place. There were lots of people laughing at him, although luckily for him not too many people recognised him.

“After sitting with his head in his hands and then trying to use his mobile phone, he eventually slid against a window, looking pretty knackered.”

Joey is in Los Angeles for business meetings as well as a holiday.

He and Sam, 23, split up last month after a four-year, on-off relationship. The pair had a huge argument at Sam’s sister Billie’s engagement party in Marbella in the summer. They got back together briefly but went their separate ways three weeks ago.

Friends say Joey is upset about the split but is now concentrating on furthering his career in the US.
